To all whom it may concern:

Be it known that I, FRANK E. FISHER, of Detroit, county of Wayne, State of Michigan,

have invented a new and useful Improvement 7 in Combined Electrical and WVater Ram for Raising WVater; and Ideclare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which itpertains to make and use it, ref erence being had to the accompanying drawing. which forms a part of this specification.

lllyinvention'consists of the combinations of devices and appliances hereinafter specified, and more particularly pointed outin the claims:

In the drawing is represented a section view illustrating my invention. 7 v I r This invent-ion is designed to combine in practice the principles of a hydraulic ram with an electric motor for the purposes of raising water from a lower to a higher elevation. In the ordinary hydraulic ram the momentum .of the water opens and closes a clack-valve with a certain escape or waste of water at this point. This invention is somewhat the same in general principles, although instead of the water escaping at the clack-valve the valve is displaced, and in its stead there is employed a piston connected with an electric motor, the water serving to lift the piston at each stroke, but the piston being driven back by the motor.

In carrying out my invention,A may represent any cistern, well, or other water-supply, the fountain-head or water-level being above the level of the clack-valve, so that in seeking its level the hydrostatic pressure will serve to force the piston at each stroke to its uppermost position. B is a chamber containing the hoisting apparatus. 0 is a conduit through which water passes from the source of supply to the apparatus. D is the usual air-chamber; E,the pipe through which water is raised,and which leads to any desired point of discharge. F and F are valves. G is the pipe or conduit leading to the piston H.

I represents any suitable pitman device connected with the crank i, which is driven by any suitable electric motor, J.

The operation of this device is as follows: Water entering through the conduit 0 lifts the valve F, and, passing through the pipe G, lifts or follows the piston H to its highest point. Reaching this point, the flow of water is thereby ated June 9, 1885.

suddenly stopped. The apparatus now instantly operates on the principle of the hydraulic ram; the momentum of the water causes a small amount to be thrown into the chamber D; the water recedes slightly in the passage G; the valves F and F are closed. But to permit the water to recede slightly in the passage G, in imitation of its action in an ordinary ram, it is necessaryto relieve the counteracting vacuum that would otherwise be formed 'beneath the piston H. This is accomplished by the motor, which forces the piston down so as to follow the waterclosely, and so leaves the conditions at this point the same as they would be in the ordinary ram when the clackvalve has dropped by its gravity. The operation is now repeated and more water forced by its own momentuminto the air-chamber D.

the discharge-pipe It will be observed that the piston, H;does not itself operate toforce the water into the air-chamber; butthis is accomplished by the momentum of the water, and that the function of the motor is simply to cause the piston to move in imitation of the-usual clack-valve, and to preserve at this point the same conditions that exist inthe usual clack-valve without any escape of water.

This device has a very wide applicationas,

for instance, in cities where the water-pressure is sufficient to bring the water to the basement or some floor above, yet is not sufficient to lift it to the upper apartments of the building. This device can there be readily located near or below the point to which the water naturally rises in the water-pipes, and serve to hoist the same to the floors above. So,also, where there is a wellor cistern,the device may be located, substantially as shown in the drawings, in a chamber partially submerged beneath the water, and in this way the device is brought into condition to operate normally. Upon starting the motor the water can thereby behoisted from the well or cistern and delivered at any desired point in the adjacent building orbuildings.

I have found in practice that with a very small. motor run from a very moderate battery a device of this character will lift the water to a considerable distance and discharge the same This air, being compressed, reacts in the usual way to force the water up and out from in considerable volume without any waste or overflow, such as is necessary in a hydraulic substantially the same as the action within a 1 hydraulic ram. I therefore wish it understood that my claim contemplates, broadly, such combined external motor and hydraulic ram. I would also have it understood that while I illustrate the invention and purpose to employ it always in connection with an electric motor, yet there might be employed instead of the electric motor any other form'of motor, and this I would have comprehended as equivalents when I use the term electric motor. The motor serves to move the piston H in imitation of the movements'of the clack-valve in the ordinary ram, the motion being faster or slower,according as the motor moves with greater or less speed. I

Instead of employing this device in a well or cistern, or in connectionwith a water-supply system, it is clearly applicable in the case tion in the presence of two witnesses.

of a drive-well,or other similar Artesianwell,

in which the water .rises to a pointto or above a the piston H, in which casean enlarged well mi ghtbe dug about the upper endof the drivewell sufiicient to accommodate the apparatus, which could be walled with cement or otherwise made dry and imperviousto surface-water. f

What I claim is 1. The combination, with a hydraulic-ram mechanism, of a piston in the place of its ordinary clack-valve, the said piston actuated, in

imitation of the movements of said clack-valve, by an external motor, substantially as and for the purpose described.

2. The combination, with ,a hydraulic-ram mechanism, of a piston in the place of the ordinary clack-valve, said piston adapted to be actuated, in imitation of the motion of said clack-valve, by an exterior electric motor, substantially as and for the purpose described.

3.- In connection with a head of water above the level of the piston, and combined with the mechanism of a hydraulic ram, a piston in the place of its clack-valve, and an external motor adapted to drive said piston alternately downward, the construction being such that the hydrostatic pressure will alternately lift the piston on its upstroke, substantially as and for the purposes described.

4. The combination, with a well or cistern,

of a'chamber s'ufficiently submerged to bring the head of water above the piston H, the said jchamber provided with hydraulic-ram mechanism, wherein the piston H takes the place of the usualclac'k-valve, the said piston connected with and adapted to be operated by an exterior electric motor, substantially as and for the purpose described.

In testimony whereof I sign this specifica- FRANK FISHER.
